Abstract
At airports in cold, snowy regions, winter runway surface conditions that prevent airplanes from landing may occur because of decreased skid friction coefficient due to snow and ice, causing inconvenience to users. To improve the skid resistance of runways, the authors focused on high-performance SMA, which forms a rough pavement surface, and considered its application as a surface mixture for runways through laboratory experiments and test construction. The results demonstrated that the technique was effective in improving the friction coefficient under conditions of slush or black ice on the runway surface. In the laboratory experiment, which evaluated freezing and thawing unique to cold, snowy regions as well as durability and other properties, high-performance stone mastic also displayed a level of performance equaling or surpassing that of dense-grade asphalt concrete 20F. a standard surface mixture. SMA's effectiveness as a measure for winter runway surfaces in cold, snowy regions was confirmed.
